corn earworm on hemp stem

The corn earworm (Helicoverpa zea) is an emerging pest of commercial hemp production throughout the U.S. Boring through stalks and feeding on reproductive structures, this pest presents several management challenges for hemp producers. While integrated pest management strategies for more traditional agricultural crops are established, much work is still needed to develop effective IPM for the corn earworm in hemp. Shown here is a corn earworm larva that has tunneled into a hemp plant stem. (Photo originally published in Britt et al 2021, Journal of Integrated Pest Management)
